-s now means *disable* escape analysis.
Fix escape leaks for struct/slice/map literals.
Add ... tracking.
Rewrite new(T) and slice literal into stack allocation when safe.
Add annotations to reflect.
Reflect is too chummy with the compiler,
so changes like these affect it more than they should.

. replaced GCC's _builtin_return_address(0) with Plan 9's
getcallerpc(&n) which is defined as a macro in <u.h>;
8g/list.c

The fix is to add ' ' after ';' so that we match
what we used to generate.
Packages like http look for the string with
the space in it, and I don't see a reason to
be so terse.

Doing a socket/listen on an unspecified address with an unspecified
address family is likely to result in an AF_INET6 socket on an IPv6
capable system, which under OpenBSD means IPv6 only - not IPv4 *and*
IPv6. In this case trying to connect to this socket from an IPv4
loopback address is not going to end well.

When the encoder was updated to respect the ",omitempty"
struct tag options, the decoder half was never updated to know
about the new struct tag format. (the format is now an optional
name, followed by zero or more ",option" strings)
This only affected people who used ",omitempty" along with
a field name. In that case, the serialized JSON wouldn't
decode to the original value.

This introduces new APIs.
- DialConfig can open client connection using Config, so user can specify protocol version, tls.Config if necessary.
- Message can be used to send/receive text/binary data in a frame.
- JSON can be used to send/receive JSON data in a frame.

Write to image.*.Pix directly in the case of RGB, RGBA and NRGBA
images. For the latter two, the file format matches the memory layout
so a simple copy can be used.
RGB image before/after:
tiff.BenchmarkDecoder 748137 ns/op (62.39 MB/s) 251256 ns/op (185.76 MB/s) x3.0
NRGBA image before/after:

- implemented stand-alone Throttle mechanism
- added new flag -index_throttle to godoc
- index throttling enables index creation when running
godoc on app engine as it keeps godoc responsive

#include "go.h" (or "gg.h")
becomes
#include <u.h>
#include <libc.h>
#include "go.h"
so that go.y can #include <stdio.h>
after <u.h> but before "go.h".
This is necessary on Plan 9.

The following testcases now pass:
`<a href=x` tests that we do not error on partial unquoted attrs.
`<a href=x ` tests that spaces do end unquoted attrs on spaces.
`<a href=''` tests that we recognize the end of single quoted attrs.
`<a href=""` tests that we recognize the end of double quoted attrs.

Pow10 failed for MinInt32 (endless loop until out of

where the result is not representable in a float64.
